Plaques à ancrage osseux en orthopédie-dento-faciale : est-il possible de les coller ?

Abstract : Skeletal Class II and III orthopedic devices have many disadvantages when they are dentoalveolar supports (worsening of the vertical direction, undesirable dentoalveolar compensation etc.). Currently, only plates with screwed bone anchors have the advantage of having a purely skeletal action to offset undesirable effects. However, these plates can only be applied from the age of 11-12 years, age from which the bone density will allow primary stability of the fixing screws, and after eruption of all permanent germs so that they are not harmed. The interception of dysmorphosis then occurs quite late. Thus, the screwed mini anchor plates are not suitable for skeletal class II treatments, which must be done before the growth spike, and the early and very early treatments for class III dysmorphoses. Therefore, the objective of this thesis was to find an alternative to this system: is it possible to glue these plates? No scientific study has been conducted so far in the field of dentofacial orthopedics (ODF) regarding the use of these tissue adhesives or bone cements to bond metallic devices to bone. The first part of this thesis gives a brief reminder on the generalities of skeletal class II and III as well as on existing devices to treat these dysmorphoses. The second part briefly describes the system of mini screw-anchored bone plates. Finally, the third part will develop the main existing tissue adhesives and bone cements, which have been the subject of much research over the past decades, to finally conclude on the adhesives, which could potentially be used as an alternative means of fixing to mini anchoring plates screwed bones.
